what is electric current?
Answers
Answer:
Electric current, any movement of electric charge carriers, such as subatomic charged particles (e.g., electrons having negative charge, protons having positive charge), ions (atoms that have lost or gained one or more electrons), or holes (electron deficiencies that may be thought of as positive particles).

The rate of flow of charge through any cross-section of a wire is called electric current flowing through it. Electric current (I) = q / t. Its SI unit is ampere (A). The conventional direction of electric current is the direction of motion of positive charge.
